Abstract : This list supplements previous errata published in Stanford reports CS551 (1976) and CS712 (1979). It includes the first corrections and changes to the second edition of volume two (published January, 1981) as well as to the most recent printings of volumes one and three (first published in 1975). In addition to the errors listed here, about half of the occurrences of 'which' in volumes one and three should be changed to 'that'. (Author)
